1 Claim. (01.285-90) Referring in detail to the drawing, the conical The present invention relates to an improvement in clean out devices.

More particularly the invention is directed to an article of manufacture to be used in connection with a liquid or gaseous pressure supply means for use in cleansing smokers articles, such as pipes and cigarette holders, to unclog sink drains, and to open up gasoline feed lines on automobiles when the gasoline ow becomes interrupted for some reason.

The invention further relates to the combination, with the other means for connecting up with a liquid or air pressure supply, of an apertured cap which can be used in such a manner as to adapt the device for application to pressure supply tubes of a greater and also of a less diameter than would otherwise be possible.

An important .ghiect of the invention is to provide in a device of the above character, an improved plug elerh'ent having both an external and internal conical taper to adapt it for emcient use in making connections with air` or liquid supply conduits of various diameters.

Other objects, advantages and features of the invention will hereinafter appear.

With these ends in view this invention consistsl in the details of construction and combination of elements hereinafter set forth and then speciiically designated in what is claimed.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction will now be described in detail.

Referring to the accompanying drawing, which illustrates what are at present deemed to be preferred embodiments of the invention,

Fig. 1 is a side elevation of the device which, as shown in this View, may be constructed internally in accordance with either of the embodiments thereof illustrated in Figs. 2 and 4. The dotted lines indicate a smoking pipe and an air hose in operative relations to the device.

Fig. 2 is a vertical mid-section of the device shown in Fig. 1.

Fig. 3 is a broken perspective of the cap or collar shown in the upper portion of Fig. 2.

Fig. 4 is a perspectiveq of a different embodiment from that shown in Fig. 2, portions being broken away in order to show internal construction more clearly. In this view an air valve is shown in dotted lines, ready to be applied to the device.

Fig. 5 is a sectional View of a third embodiment showing the same positioned in the top of a sink drain ready to apply a ushing liquid.

rubber or cork-plug 1 shown in Fig. 2 is vulcanized to a pipe 8 which extends axially therethrough from the small end thereof and projects considerably beyond the large end thereof. The small end of this plug is shown tapered to substantially a knife edge around the end of the pipe or tube 8. A cap 9 having a circular end opening i0. is shown tted upon the projecting end of the tube 8 for the purpose of bringing the tube 8 up to the desired orstandard diameter whereby it is adapted to engage in a cooperating manner with an air hose valve Il when it is desired to clean out a pipe I2. The conical face makes the plug adaptable for use with smokers pipes,

the bowl openings of which vary in both diameter and depth. The elasticity thereof makes it adaptable for use with such pipes whose bowls are irregularly caked.

The internal diameter of tubing varies, for example tin tubing has a dierent inside diameter than standard tubing and lalthough tin tubing is adaptable for use in constructing my plugs it is unadapted, without modification, to operate air valves like those which are used at service stations for illling automobile tires. For this reason it is necessary to bring the inside diameter or outside diameter to a size adaptedfor contacting with the air valve in using the device. Therefore when standard tubing of the right size is used in constructing the device (although such tubing costs more) this novel piug'will be constructed without the cap as shown in Fig. 4.

In Fig. 4 is shown a plug I3 shaped like the plug 1 except that the/ small end thereof is of va suillcient diameter to provide room therein for a conical 4recess I4 which tapers inwardly from that'end of the plug. There extends axially into this plug from its large end, a Ytube l5, which is vulcanized to 'the plug and which projects somewhat from its large end.

In Fig. 4 the plug is shown with its conical recess fitted over the end of a `tube I6, and an air valve I1 is indicated in dotted lines in readiness to be applied to the device to-direct a blast of air into said tube I6. The conical recess I4 adapts this form ofthe device for being applied in a substantially/ air tight manner to tubes varying considerably in diameter.

The embodiment of ithe invention shown in Fig. 5 differs from that shown in Fig. 2 in that the plug Zllhas' a circumferentially ribbed tube 2l extending axially therethruand said tube has a diametrically enlarged Aportion 22 near its large end which is internally screw threaded to screw on to the coupling member 2l ot a garden hose 25. The part 22 terminates in a peripheral outwardly directed ilange 23 abutting against the adjacent end of the plug. In this view the device is shown screwed on to the garden hose 25 and inserted into the mouth of the drain pipe 26 of a sink 21, preparatory to flushing out said drain pipe.

In the construction shown in Fig. 4 the mouth of the frusto-conical recess I4 is of nearly as great a diameter as the external diameter of the small end of the plug thus `providing a narrow annular compressible and expansible lip 30 at that end of the plug. Said lip may be diametrically contracted or expanded according torequirements in making a fluid or air tight fit into or over parts having passages into which theliquid or iluid is to be forced. l,

In Fig; 3 the opening I0 is formed by upsetting the end of the tube 8in such a manner as to l form an upwardly directed circumferential flange lnx.

It is to be understood that the forms oi' my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts maybe resorted to without departing from the spirit" of the'ihvention, or the scope of what is claimed. f

Having in this case described my invention, I claim:

Means for coupling an air hose Valve to a tube, comprising a conical plug of elastic material having an axial bore extending therethrough, a metal ytube inserted in said bore, said tube projecting from one end of said plug and adapted to engage and open said valve, the bore at the other end of the plug being adapted to receive a second tube, said bore being taperingly increased in diameter from the enclosed extremity of the rst tube to the smaller end of the plug to adapt it foruse on tubes of varying sizes.
